Characteristics	- Swashplate Axial Plunger Variable Pump for Closed Loop Hydrostatic Transmission - Flow rate is proportional to driving speed and displacement - Flow increases from zero to maximum with swashplate swing angle - Liquid flow direction can be changed smoothly over the middle - Two relief valves at high pressure side for overload protection - High pressure relief valve doubles as a filling valve - Built-in auxiliary pumps for refueling and control - Maximum filling pressure limited by built-in relief valve

Safety Instructions

Designed for use in closed circuit only.
Project planning and installation must be carried out by qualified personnel.
Read the corresponding manual completely before operation.
Be aware of burn risks from the axial piston unit (especially electromagnet) during operation.
Machine manufacturers must ensure safety factors of connecting components and pipes meet specified conditions.
Tightening torques must follow VDI 2230 and manufacturer specifications.

Frequently Asked Questions

What are the main applications for the A4VG series pump?

The A4VG series is widely used in engineering machinery, construction equipment, and metallurgy machinery due to its high-pressure capabilities and robust cast iron material.

What is the pressure rating for these hydraulic piston pumps?

The nominal pressure is 40 MPa (400 bar), with a peak pressure capability of up to 45 MPa (450 bar).

Which control modes are available for this pump?

We offer multiple control modes including NV (no control), DG (hydraulic direct), EZ (electric two-point), HD (hydraulic pilot), HW (mechanical servo), EP (proportional electromagnet), and DA (deceleration related).

What is the warranty period and production capacity?

The pump comes with a one-year warranty. The current production capacity is approximately 5000 pieces per year.

How is the product packaged for international shipping?

All pumps are packed in Standard Export Wooden Cases to ensure maximum protection during long-distance transportation.

Can the flow direction be adjusted on this pump?

Yes, the liquid flow direction can be changed smoothly by adjusting the swashplate swing over the middle position, making it ideal for closed-loop hydrostatic transmissions.
